//
// Updated 14 December 2009 by A Hand
// - Added the method for detecting BlackBerry Touch
// devices like the Storm 1 and 2.
//
// Updated 5 December 2009 by A Hand
// - Fixed the DetectPalmOS method. It should filter
// out WebOS devices.
//
// Updated 8 November 2009 by A Hand
// - Added the deviceWebOS variable.
// - Added Palm's WebOS to the DetectPalmOS method.
// - Created a new method to check for Palm's WebOS devices.
// - Added Palm's WebOS to the DetectTierIphone method.
//
// Updated 4 April 2009 by A Hand
// - Changed the name of the class from DetectSmartPhone to UAgentInfo.
// New name is more consistent with PHP and JavaScript classes.
// - Added a method to detect Opera Mobile and Mini. Opera Mobile is new.
// - Updated the algorithm for detecting a Sony Mylo.
// - Added Android to the DetectTierIphone method.
// - Updated comments for Detect Tier methods.
